Steps to Grow Begonia Doublet
1. Choose the Right Location
- Select a spot with partial shade or bright, indirect light.
- Avoid direct afternoon sun, which can scorch leaves.
2. Prepare the Soil
- Use a well-draining soil mix rich in organic matter.
- For pots, choose a mix designed for flowering plants or mix regular potting soil with perlite.
- Ensure the soil has a slightly acidic to neutral pH (5.5–7).
3. Planting
- Outdoors: Plant after the last frost when the soil temperature is consistently warm.
- Indoors: Use a container with drainage holes.
- Space plants 8–12 inches apart to allow airflow and prevent fungal issues.
4. Watering
- Keep the soil evenly moist but not waterlogged.
- Water at the base to avoid wetting the foliage, reducing the risk of disease.
- Allow the top inch of soil to dry between waterings.
5. Fertilizing
- Apply a balanced liquid fertilizer (10-10-10) every 2-3 weeks during the growing season.
- Reduce feeding in winter if the plant is kept indoors.
6. Pruning and Maintenance
- Remove spent blooms regularly to encourage continuous flowering.
- Trim leggy stems to maintain a bushy appearance.
- Inspect for pests like aphids or whiteflies, treating with insecticidal soap if necessary.
7. Overwintering
- In Cold Climates: Bring potted begonias indoors before frost.
- Place in a bright location, reduce watering, and avoid fertilizing during dormancy.
- Outdoors: Treat as annuals or dig up and store tubers in a cool, dry place.
Propagation
- Stem Cuttings:
- Take 4-6 inch cuttings and remove lower leaves.
- Place in moist potting mix or water until roots develop.
- Seed: Start seeds indoors 12 weeks before the last frost. Keep the soil consistently moist and warm for germination.
Common Issues
